A) 5000
B) 6000
C) 6400
D) 7000
Correct Answer: C
Solution :
[c] Let rate of increase in population = r% p.a. Then \[4800=3600{{\left( 1+\frac{r}{100} \right)}^{5}}\] \[\therefore \] \[{{\left( 1+\frac{r}{100} \right)}^{5}}=\frac{4800}{3600}=\frac{4}{3}\] Population in the next 5 years will become \[4800\times \frac{4}{3}=6400.\]You need to login to perform this action.
